Other valuable DOD Coding Information Regarding Messages:
Trying to determine who a certain player is spectating?
Register this: register_event("StatusValue","on_StatusValue","b")
And here is the on_StatusValue function:
	public on_StatusValue(id){
	new targetid = entity_get_int(id, EV_INT_iuser2)
	if( targetid == 0 )
	return PLUGIN_CONTINUE
	// Do Stuff here
	return PLUGIN_CONTINUE
	}
Note: Even though StatusIcon isn't registered as a message, it is possible to register this message (I lost the code to do this, but I have done it)
